Now, here's my contribution to an idea on tier names.
Why not keep the same names we already have. Just move the members to their perspective tiers through levels.
The Master tier would include the top players, or the elite players period.
The Pro, and Pro+ tiers would include those Masters with a lower average.
The Amateur, and Amateur+ tier would be those players at the Pro level, or just below.
The Hack tier is for beginners (new members)
Implement this with the other ideas WGTalex laid-out in the beginning of this thread.
That's my 2 cents. I tell you, it's a complex idea, but one we all need to see in the game. : )
